I’m writing a full series on setting up your Mac for Magnto ecommerce development, I should probably start with the first step – installing MAMP on a Leopard Mac, even if it’s a quite basic and hopefully self evident.
Maybe one of the less obvious things is that you do not need MAMP pro to get virtual hosting set up in Apache on a Mac, but it will require you to work with Apache config files as described in my post on setting up virtual hosts in apache on MAMP.
